Intel NUC Board NUC5i5MYBE Technical Product Specification
58
2.2.4.2 Add-in Card Connectors
The board supports M.2 2230 (key type E) and 2280 (key type B) Modules; also supports M.2
2242 Modules
• Supports M.2 SSD SATA drives
• Maximum bandwidth is approximately 540 MB/s
• Supports M.2 SSD PCIe drives (PCIe x1 and x2)
2.2.4.3 Power Supply Connectors
The board has the following power supply connectors:
• External Power Supply – the board can be powered through a 12-19 V DC connector on the
back panel. The back panel DC connector is compatible with a 5.5 mm/OD (outer diameter)
and 2.5 mm/ID (inner diameter) plug, where the inner contact is +12-19 (±10%) V DC and the
shell is GND. The maximum current rating is 10 A.
NOTE
External power voltage, 12-19 V DC, is dependent on the type of power brick used.
• Internal Power Supply – the board can alternatively be powered via the internal 12-24 V DC
2 x 2 power connector, where pins 1 and 2 are +12-24 (±10%) V DC and pins 3 and 4 are
GND. The maximum current rating is 10 A.
The connector used is Molex Micro-Fit (3mm pitch), right-angled, 4-pos/dual row (2x2).
